Objective To investigate the relationship between brain natriuretic peptide ( BNP)/ N-terminal pro-brain natriuretic peptide ( NT-proBNP) and New York Heart Association ( NYHA) classification, left ventricular structure and function, and explore the value of BNP/ NT-proBNP in the diagnosis of heart failure in the elderly. Methods Fifty-five elder patients with heart failure were selected (NYHA II, n = 15; NYHA III, n = 25; NYHA IV, n = 15) (heart failure group), and another 16 elder people with NYHA I were served as control group. The plasma mass concentrations of NT-proBNP and BNP were detected by electrochemiluminescence immunoassay and immunofluorescence method, respectively, and the structure and function of left ventricle were examined by echocardiography. Results The levels of plasma BNP and NT-proBNP increased with NYHA grades, were negatively correlated with LVEF (P <0.001), and were positively correlated with LVST, LVEDD, LAD and LVMI( P < 0.05). The area under the curve of BNP in diagnosis of heat failure was 0. 879 (P < 0.001), and that of NT-proBNP was 0.914(P < 0.001). Conclusion Both plasma BNP and NT-proBNP can be used to evaluate the heart function of patients with heart failure, and are useful tools for diagnosis of HF in the elderly.

Bilingual teaching is one of education reform in China.The essay analyzed the necessity of bilingual teaching and clarified the reason why it can procced in microbiology.Search after the way in microbiology course according to the character of college in western China.The practice accumulated experience for bilingual teaching.

Objective To assess the diagnostic value of coronary CTA (CCTA) combined myocardial CT perfusion imaging (CTP) in coronary artery disease (CAD) with Meta-analysis.Methods Chinese and English literatures evaluating CCTA combined CTP in diagnosis of CAD in PubMed,Wed of Science,Cochrane Library,China National Knowledge Infrastructure (CNKI) and Wanfang Periodical Database from inception to December 2016 were searched.The extraction was conducted according to the criteria for diagnostic recommended by Cochrane Method Group.The quality of included studies was assessed with quality assessment of diagnostic accuracy studies-2 instrument.The statistical analysis was performed by Meta-disc 1.4 software,the diagnosis efficacy was calculated and the symmetric receiver operating characteristic curves (SROC) was drawn to obtain the area under curve (AUC).Results Five studies involving a total of 611 vessels were included.The pooled sensitivity (SEN),specificity (SPE),diagnostic odds ratio (DOR),positive likelihood ratio (PLR),negative likelihood ratio (NLR) were 0.96 (95％CI [0.92,0.98]),0.91 (95％CI [0.88,0.94],206.14 (95％CI [100,424.94]),9.33 (95％CI [5.57,15.61]),0.06 (95％CI [0.03,0.13]),respectively.The AUC of SROC was 0.977.Conclusion CCTA combined CTP has significant value in diagnosis of CAD.

Objective To explore the predictive values of the levels of blood lipids ,liver function and estrogen for the fetal dis‐tress in intrahepatic cholestasis of pregnancy (ICP) patients .Methods The indicators of blood lipids ,liver function and estrogen of mild IPC group ,severe ICP group and control group were detected respectively ,and the results were analyzed .Results The levels of triglycerides ,total cholesterol and low‐density lipoprotein were positively related to estradiol levels .Multivariate logistic regres‐sion analysis showed that cholyglycine (OR=8 .24 ,P=0 .01) and estradiol(OR=4 .46 ,P=0 .02) were significant for prediction of fetal distress in ICP patients .Conclusion Estradiol and cholyglycine levels may be better indicators for the prediction of fetal dis‐tress in ICP patients .

Objective To evaluate the diagnosis and surgical treatment of parathyroid carcinoma (PTC). Methods Clinical data of 8 PTC cases were analyzed retrospectively. Results PTC accounted for 5. 7% of patients with primary hyperparathyroidism (PHPT) in our hospital. There were 4 men and 4 women. Male patients had younger mean onset age compared with female patients. The disease history of PTC was shorter than PHPT of benign causes. Six patients were admitted for acute hypercalcemia. Seven patients complained of palpable neck mass. Calcium level was 3.75?0.34 mmol/L,and PTH level was 1429.47?841.75 pg/ml. Frozen section established diagnosis in only one case. Four patients underwent radical en bloc resection. Other 4 cases received routine simple parathyroidectomy, 3 patients developed recurrence in 12 - 18 months postoperatively. Conclusions Acute hypercalcemia is common in PTC. Frozen biopsy diagnosis is not satisfactory. An initial en bloc resection of tumor and adjacent structures contributes most to the prognosis.

BACKGROUND: Classic isolation method of bone marrow mesenchymal stem cells (BMSCs) is Percoll density gradient centrifugation. Blood cell component was removed. However, this method is complicated. Preparation density was needed when isolating dog bone marrow. Moreover, centrifugation was frequent, which had a great damage to cells. OBJECTIVE: To establish methods of the isolation, proliferation, culture and osteoinduction of canine BMSCs, and observe the in vitro proliferation and ability to osteoinduction differentiation. METHODS: 10 mL bone marrow was extracted from dog posterior superior iliac spine, heparin anticoagulation, diluted using Hanks juice, treated with 1.077 g/mL Ficoll solution 3 mL, and centrifuged at 2 000 r/min for 20 minutes. Karyocytes were absorbed to form white cloudlike layering interface, and then centrifuged twice using DMEM supplemented with fetal bovine serum, incubated at 12×10~4/cm~2 at 37 ℃ in a 5% CO_2 incubator. Following subculture, cells were incubated in DMEM containing dexamethasone, β-sodium phosphoglycerol and ascorbic acid 2-phosphate. Immunocytochemical staining and immunofluorescence staining were utilized to detect osteocalcin, osteopontin and type Ⅰ collagen expression in osteoblasts. Alkaline phosphatase staining and alizarin red staining were performed. RESULTS AND CONCLUSION: 1.077 g/mL Ficoll density gradient centrifugation was used to isolate karyocytes that were significant compared with Percoll solution. Obtained BMSCs had high purity, good growth and the mean doubling time was 24 hours. Following in vitro osteogenic incubation of dog BMSCs, osteocalcin, osteopontin and type Ⅰ collagen showed positive expression. Alkaline phosphatase staining demonstrated bluish-green cytoplasm. Alizarin red staining showed red nodes in extracellular matrix, and could differentiate into osteoblasts in vitro.
